1. 1. Glacial history of Northeast Greenland: cosmogenic nuclide constraints on chronology and ice dynamics

   Författare :Lena Håkanson; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Jameson Land; Store Koldewey; Scoresby Sund; Ice dynamics; Glacial history; Cosmogenic; Greenland Ice Sheet;

   Sammanfattning : The aim of this thesis was to use cosmogenic exposure dating to investigating whether highly weathered landscapes in the Northeast Greenland fjord zone have developed during prolonged ice free conditions or have been preserved beneath cold-based ice. Previous work along the Northeast Greenland coast has presented two conflicting hypotheses for the extent of the Greenland Ice Sheet during the last glacial maximum (LGM). LÄS MER

3. 2. Glacial geology and palaeo-ice dynamics of two ice-sheet margins, Taymyr Peninsula, Siberia and Jameson Land, East Greenland

   Författare :Helena Alexanderson; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ice dynamics; Pleistocene; Arctic Siberia; East Greenland; Sedimentology; Physical geography; Sedimentologi; pedology; geomorphology; klimatologi; kartografi; marklära; geomorfologi; cartography; Fysisk geografi; ice-marginal processes; glacial history; climatology;

   Sammanfattning : The North Taymyr ice-marginal zone (NTZ) on the Taymyr Peninsula, Arctic Siberia and the Ugleelv Valley on Jameson Land, East Greenland, have been investigated with the aim of reconstructing the glacial history, including depositional processes and environments. Geomorphological, sedimentological, stratigraphical and remote sensing methods have been combined to give a comprehensive view of developments in the two areas. LÄS MER
